TL082 Op-Amp IC can be used for audio pre-amplification and it can provide an edge in terms of sound quality because of its price compared to its specs. So, if you are looking for an Op-Amp IC with Quad package and JFET driven then this IC might be the right choice for you. These devices also exhibit low noise and offset voltage drift. Other than that, these amplifiers may be used in applications such as high-speed integrators, fast D/A converters, sample and hold circuits and many other circuits requiring low input offset voltage, low input bias current, high input impedance, high slew rate and wide bandwidth. Also, this Op-Amp has low noise and harmonic distortion making it an ideal choice for audio pre-amplifiers. The main distinguishing feature of the TL082 Op-Amp is that they incorporate high-voltage JFET and bipolar transistors which helps the transistor to have very high input impedance and low bias current. The TL082 is a Dual Package Operational Amplifier, meaning it has two Op-Amps inside it and each Op-Amp can be used independently.
Note: Complete Technical Details can be found in the TL082 IC datasheet given at the end of this page. Internally Trimmed Offset Voltage: 15 mV.Common mode Rejection Ratio CMRR: 100dB.Typical Operating Voltage: +18V to -18V.
Ground or Negative (Dual Polarity Supply)
In addition, well-matched high voltage JFET input devices provide very low input bias and offset currents. This device requires a low supply current yet maintains a large gain bandwidth product and fast slew rate. The devices feature high slew rates, low input bias and offset current, and low offset voltage temperature coefficient.The TL082 Op-Amp is a low cost, high speed, dual JFET input operational amplifier with an internally trimmed input offset voltage.
The TL072 is a high speed J-FET input dual operational amplifiers incorporating well matched, high voltage J-FET and bipolar transistors in a monolithic integrated circuit.
